L-shaped wharf construction method

Abstract

The invention relates to an L-shaped wharf construction method. The construction method comprises a plurality of general berths and a plurality of grocery berths, the construction process of the general berths sequentially comprises the steps of foundation trench excavation, foundation bed riprapping, foundation bed tamping, foundation bed leveling, caisson prefabrication, transportation and installation, sand backfilling in a box, foundation bed front edge rock backfilling, foundation bed rear inverted filter layer and box top construction, box rear backfilling construction to form a working face and a cast-in-place breast wall, box rear backfilling to the designed elevation, vibroflotation, and residual auxiliary engineering construction; and the construction process of the grocery berths sequentially comprises the steps of surface cleaning, preloading, unloading, combined steel sheet pile driving on land, combined steel sheet pile driving on water, sheet-pile wall rear excavation and block stone backfilling, anchorage wall construction, breast wall cast-in-place and pull rod installing, track beam construction, ground backfilling and road construction. The construction method has the advantages that the comprehensive cost is low, ships of different tonnages can berth conveniently, and the loading and unloading efficiency of berths is improved.

Description

technical field [0001] This application relates to the field of water conservancy engineering, in particular to an L-shaped wharf construction method. Background technique [0002] A wharf is a hydraulic structure for ships to dock, load and unload goods, and passengers. [0003] During the actual operation of the terminal, the berths of the terminal are often not docked by a single ship type. When a small-tonnage ship berths at a large-tonnage berth, it will reduce the efficiency of berth loading and unloading, and the utilization rate of the berth is low. In order to improve the loading and unloading efficiency of the berth, It is necessary to build berths of large tonnage and also berths of small tonnage to facilitate the berthing of ships of different tonnages and improve the loading and unloading efficiency of berths. [0004] In view of the related technologies mentioned above, the inventor thinks that there is an urgent need for a wharf that can accommodate ships of ...

Problems solved by technology

[0003] During the actual operation of the terminal, the berths of the terminal are often not docked by a single ship type. When a small-tonnage ship berths at a large-tonnage berth, it will reduce the efficiency of berth loading and unloading, and the utilization rate of the berth is low. In order to improve the loading and unloading efficiency of the berth, It is necessary to build large tonnage berths and small tonnage berths at the same time, so as to facilitate the berthing of ships of different tonnages and improve the loading and unloading efficiency of berths.
